Improper Authorization in Elastic Cloud Enterprise can lead to Privilege Escalation where the built-in readonly user can call APIs that should not be allowed. The list of APIs that are affected by this issue is:

post:/platform/configuration/security/service-accounts delete:/platform/configuration/security/service-accounts/{userid} patch:/platform/configuration/security/service-accounts/{userid} post:/platform/configuration/security/service-accounts/{userid}/keys delete:/platform/configuration/security/service-accounts/{userid}/keys/{apikeyid} patch:/user post:/users post:/users/auth/keys delete:/users/auth/keys delete:/users/auth/keys/all delete:/users/auth/keys/{apikeyid} delete:/users/{userid}/auth/keys delete:/users/{userid}/auth/keys/{apikeyid} delete:/users/{username} patch:/users/{username}

Improper neutralization of special elements used in a template engine in Elastic Cloud Enterprise (ECE) can lead to a malicious actor with Admin access exfiltrating sensitive information and issuing commands via a specially crafted string where Jinjava variables are evaluated.
